In a prior post, I provided data on patent application pendency — looking at applications from their filing date to the issue date. The chart adds an additional perspective — also calculating the pendency beginning with the application priority date. Looking simply at filing-date to issue-date, average pendency is hovering just over three years. However, the average U.S. patent issues more than five years after its original priority application filing date. The chart below presents the information in the form of a histogram showing the distribution of pendency for patents issued thus far in 2014.
